i just got myself some lead slugs and was wondering do i remove my choke tube to shoot these, and if not what would be the best choke tube to have in while fireing these??

Don't remove the choke tube, just shoot it with the most open choke tube you have.

ok thanks.

Shoot with an improved cylinder if you can, don't shoot it out of anything tighter then a modified, and even that might be pushing it

Improved usually provides the tightest groups.
